God contacts men through their spirits.
When the Word of God is preached to a sinner who has never heard the Gospel and conviction comes upon him, it's not a physical feeling - neither is it a mental something, because he may not even understand it - but it's down deep on the inside. The Spirit of God through the Word of God is contacting the spirit of that sinner!
When that man responds to the call of God and the Gospel message, his spirit is born again. His spirit is recreated by receiving eternal life.
Receiving eternal life is the most miraculous event in life. It's called the New Birth. It's called the new creation. It is, in reality, God imparting His very nature, substance, and being to our human spirits.
It is described in 2 Corinthians 5:17 and 18. The New Birth is God actually giving spiritual birth to a man. And this instantaneous New Birth takes place, not in the body, not in the soul, but in the spirit of man!
The spirit of man becomes a brand-new, miracle creation in God!
Confession: I am a brand-new, miracle creation in Christ. God gave me the gift of eternal life. He imparted to my spirit His very nature, substance, and being. Residing in my own spirit is everything I'll ever need to put me over in life.
